My normal elo is FAR too high for me to enjoy myself. I can only play two characters in there and have any success. My opponents are usually mostly gold plat+ or premade extras. I get utterly crushed when I play anything I'm not used to.

My elo 'volatility' is, as far as I can tell at near-zero. Thus, it would take me hundreds of games to lower it.

I tried playing with a lower normal MMR friend and all it did was lower the average level to his, and put a platinum on the enemy team for me to 'enjoy'.
